If there are 60 males in a class of 120 students, what is the percent of females in the classroom?

Answer:

D: x^(6) + 27y^(9)

Step-by-step explanation:

A) 3x^(9) - 64y^(3)

The first term is raised to the power of 9 and has a coefficient which cannot also be expressed as a cube while the second term is raised to the power of 3 but has a coefficient that can be expressed as a cube. Thus the entire equation cannot be simplified to cubes as the first term cannot be expressed a cube.

B) 15x^(21) - 64y^(3)

Similar to the reason given in A above, the first term cannot be expressed as a cube.

C) 27x^(15) - 9y^(3)

In this one, the first term can be expressed as a cube while the second one cannot be expressed as a cube because 9 cannot be expressed as a cube.

D) x^(6) + 27y^(9)

This can be expressed as;

(x²)³ - (-3y³)³

This is therefore a difference of cubes

Answer:

x=11

mMN=65

mNP=115

mNQP=245

Step-by-step explanation:

10x-45=6x-1

4x=44

x=11

mMN 6(11)-1=65/ 10(11)-45=65

mNP 180-65=115

mNQP 65+115+65=245

Answer:

1442.9 = 1.4429 x 10 ^1000

Step-by-step explanation:

PEMDAS

4.3 × 107 + 9.1 × 108 = _____ x 10 ^----

(4.3 × 107) + (9.1 × 108) = _____ x 10 ^---

460.1 + 982.8 = _____ x 10 ^----

1442.9 = 1.4429 x 10 ^1000

This is the right answer, I think you may have forgotten to put the ^.  

Answer:

9.53 × 108

Step-by-step explanation:

Make sure both numbers have the same exponent

4.3 × 107 = 0.43 × 108

Then add the coefficients

0.43 × 108 + 9.1 × 108 = 9.53 × 108

Answer:

the side length of the cube is 4.10

Step-by-step explanation:

The computation of the side length of the cube is shown below:

As we know that

The volume of the cube is side^3

So,

69^3 = s^3

Now the side length of the cube is

= ∛69

= 4.10

Hence, the side length of the cube is 4.10

The same would be considered and relevant too

The above formula should be applied for the same

Answer:

Widgets: 12

Wombats: 15

Step-by-step explanation:

Let x represent widgets

y represent wombats

Set up the equations

(1) x + y = 27

(2) 0.75x + 1.25y = 27.75

Solve equation (1), x + y = 27 for x

x = 27 - y

Substitute 27- y for x into equation (2)

0.75(27 - y) + 1.25y = 27.75

0.5y + 20.25 = 27.75

0.5y = 7.5

y = 15

Substitute 15 for y into equation (2)

x = 27 - 15

= 12

Answer:

65

Step-by-step explanation:

Do the opposite of what the question gives you.

Sara has the number 11. She divided by 7, so you would multiply by 7:

11 x 7 = 77

Next, Sara added 12, so you will subtract by 12:

77 - 12 = 65

65 is the number Sara was thinking of.

Answer:

840

Step-by-step explanation:

Given the date:

Birth date = 12/24/2002

Number of digits = 8 = 8! = (8*7*6*5*4*3*2*1) = 40320

Repeated digits :

digit 2 = 4 times = 4! = (4 * 3 *2 * 1) = 24

digit 0 = 2 times = 2! = 2*1 = 2

Therefore the number of 8 digit codes that can be formed is :

8! / (4! * 2!)

40320 / (24 * 2)

40320 / 48

= 840

Hence, 840 8 digit codes can be formed

Answer:

B

Step-by-step explanation:

A has 2 it crosses the x axis 2x

B Has 1.

C has 2

D has none since it never touched the x axis

Option B is correct.

If the graph of quadratic function crosses x - axis at two points then that function has two zeros.

Therefore, Option B graph represent a quadratic function that has only one zero.
